It measures motion and provides roll, pitch and heave, without internal GNSS receiver.\u003c\/p\u003e\u003ch3\u003eIntegration\u003c\/h3\u003e\u003cp\u003eEthernet 10\/100, RS-232\/RS-422 link, web interface and 8 GB logger. Standard output reaches 200 Hz. Power input 9 to 36 V DC, power consumption under 3 W. Housing 100 x 86 x 58 mm, 400 g, IP68. Allow space for connectors.\u003c\/p\u003e\u003ch3\u003eAccuracy and limits\u003c\/h3\u003e\u003cp\u003eThe A2 datasheet and manual typically list 7 µg\/√Hz accelerometer noise and 2 µg bias stability. These raw sensor figures do not guarantee the final accuracy of each measurement. SBG’s web page shows different bias figures: the ordered configuration must be confirmed before final technical selection. Absolute heading requires an appropriate external reference; aided navigation accuracies are not guaranteed without assistance.\u003c\/p\u003e\u003ch3\u003eContents and accessories\u003c\/h3\u003e\u003cp\u003eUnit only, sold on quotation. Main cable, power cable and commissioning accessories are offered separately. Protect bare cable terminations and verify the vibration profile and marine constraints of each installation location.\u003c\/p\u003e\u003ch3\u003eVibration and usable bandwidth\u003c\/h3\u003e\u003cp\u003eLower white noise does not ensure better measurement across every vibrating machine. For the A2, the manual lists a vibration rectification error VRE under 200 µg\/g² over 20 Hz to 2 kHz. Published vibration qualification is 3 g RMS over this range. The actual vibration profile, rigid mounting and filtering must be validated; a standard 200 Hz output does not preserve a usable bandwidth of 433 Hz.\u003c\/p\u003e\u003ch3\u003eManufacturer documentation\u003c\/h3\u003e\u003cp\u003e\u003ca href=\"https:\/\/support.sbg-systems.com\/sc\/hp\/files\/latest\/108533406\/108533756\/1\/1742981153168\/EKINOXHM-v1.4.pdf\"\u003eSBG Ekinox hardware manual, revision 1.4\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/www.sbg-systems.com\/wp-content\/uploads\/SBG-Ekinox-Series-MK005EN.pdf\"\u003eOfficial Ekinox Series datasheet\u003c\/a\u003e\u003c\/p\u003e","brand":"SBG Systems","offers":[{"title":"Default Title","offer_id":57462726951252,"sku":"100-2122","price":0.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/main_11458d5a-8f59-43f3-b072-083c2d3642ce.png?v=1791385414","url":"https:\/\/skysat.fr\/en\/products\/sbg-ekinox-a-marine-mru-a2-8g","provider":"Skysat","version":"1.0","type":"link"}
